I could have used a XL likely for 38C-D chest. This works for sure and will be used as my primary for more intense workouts, but the band does ride up a bit. I will say, this fabric is definitely the closest to non-sustainable I’ve experienced. So glad it’s healthy for me and performs!

I think this bra has a really nice material and is decently supportive. I'm a 32DDD and purchased a Medium. It fits well but definitely is not supportive enough for HIIT or more intense cardio. Works well for lower impact activities like pilates, yoga, strength training, etc. Would love to see a bra that's for higher impact/larger chests!

This is my new FAVORITE sports bra! I have been on the search for a clean brand sports bra and I could wear this all day and night. So buttery soft and ultra supportive- I like HIIT exercises, riding dirt bikes and am a volleyball coach and this sports bra support is 100% with all those activities. I run between a medium/large so I ordered a large and its the perfect fit, not too big. Do yourself a favor and try it!

Although I waited a while to receive it (they’re so popular!) I LOVE this sports bra. The elasticity, compressive quality and overall fit are perfect! 13/10 recommend!

I’ve been looking for a eco friendly sports bra that offers good support, looks great and feels great. I finally found one! I’ve put this bra to work in spin class where I am sweating and moving a lot. I’ve ordered these in all the colors available now.

I have been impressed so far with the sports bra. I ordered a M, usually wear either a M or L (36C), and it’s a little on the tighter side. But great for higher impact workouts. I like the Marlin color, feels a bit like a bright periwinkle. The material feels more synthetic, but I love that I know there aren’t toxins in it. I sweat a lot and it shows. But I never workout just in a sports bra so that doesn’t make a difference for me. Overall, I’m very satisfied.
